of my invention is to pro- 10 vide a construction in which the sash maybe made up as a continuous unitary structure, without requiring`separation thereof into two or more parts for insertion of the glasstherein.

A further object isto provide a construction in which the glass may beremoved or replaced while the sash `remains in its usual operativeposition Within the window casing.

My invention further relates t-o the provi sion of simple and convenientlocking means for holding the glass in the Sash, tothe provision ofeffective cushioning devices for the glass7 to an improved sashconstruction and to certain arrangements and combinationsof parts whichwill be hereinafter described and more particularly pointed out in theappended claims. Q

locking Referring to the drawingsmy improved metal window sash comprisesframe members 20, which are permanently assembled to be Continuousaround the entire sash. These frame members are preferably made up ofSheet brass or other suitable metal, bent or pressed to the crosssectional outlines indicated in Figs. 2, 3, and 4.

While I have indicated the frame members 2O as made from a certainnumber of piecesl of sheet metal, it will be understood that theconstruction may be varied and that the different frame members may bemade of one, two or more pieces of sheet metal as may be preferred underdifferent conditions.

I preferably provide recesses 2l in the frame members 20 to receivecorner pieces 22 (Figs. 6 and 7) which fit snugly in said recesses andfirmly retain the frame members in accurate alignment, also stiffeningand strengthening the sash at the corners thereof.

Fig. 2 shows a section of one of the side frame members, with the sidesof the frame member extended outward, as indicated at 243 to provideextensions at each side of a sash guide Qlmounted on a casing frame 25.

In Fig. 3, I have shown a cross section of the top frame member, withthe sides of the member bent inward and locked together to form a smoothcontinuous top edge for the frame, as indicated at 26.

In Fig. Ll, I have shown a cross section of the bottom frame member,with the sides projected downward and bent inward to provide lugs or'flanges 27 to receive a cushioning member or backing strip 28.reinforcing flange member 29 may be inserted between the projectedportions 27.

The specific construction of the outer edge portions of the framemembers forms no part of my present invention andis shown for pur posesof illustration only.

At the inner edges of each sash member 2O I provide an inwardlyprojecting flange 34 (Fig. 2) and also a. depressed groove or recess 35.y The glass G is retained in position against the flanges 34k and ispreferably provided with a U-shaped cushioning member 36 which litsaround the edge of the glass and forms a yielding engagement with theflanges 34 and With the inner edge walls of the members 20.

After the glass is thus inserted in the sash, locking bars 40, 41, 42and 43 are inserted in the grooves-35 in predetermined order as will behereinafter described. The side bars 41 and 42 are provided with shortprojecting lugs 45 at one end and with notches or recesses 46 providingshoulders 47 at the opposite ends. The ends of the top bar 43 are cutaway on an upward curve as indicated in Fig. 12 and all of the lockingbars are provided with small holes 48 near one or both ends thereof forpurposes to be described.

Having described the details of construction of my improved window sash,I will now describe the method of assembling thc parts to secure theglass in the frame.

The cushioning member 36 is applied around the four sides of the glass Gand the glass is then inserted in the frame rwith a portion of thecushioning member VseatedV against the inwardly projecting flange 34.The locking bars are then-inserted in the following order The bottom bar40 Vis first slipped in the groove 35 along the bottom frame member, asindicated in Figs. 1 and 4. A side bar 41 is then Vinserted by hookingits end lug 45 over the end of the bar 40, as indicated in Fig. l, andthen swinging the bar into place about the lug 45 as a pivot. The sidebar 42 is then similarly inserted, as indicated in Figs. l and 2, andthe top bar 43 is then placed in positionv by inserting the left handend into the notch 46 of the bar 4l and causing it to engage theshoulder 47. The opposite end of the bar 43 engages the inner face ofthebar 42 and forces the bar yieldingly outward as the bar 43 is pushed'upward. If necessary, additional force maybe exerted against the bar 42tov swing it outward to permit the upward movement of the bar 43. i

As soon as the end ofthe bar 43 passes the ing engagement with the barV43, the bar4 42 is preferably given a slight longitudinal curve, asindicated in Fig. 9, the bar being straightened as the bar 43 is snappedinto position. 1 l In Fig. 11, I have indicated a slightly modifiedconstruction in which the side bar 42a is bevelled or tapered on therear edge at its upper end so that it may be readily forced outward whenthe bar 43 is inserted.

Having inserted the locking bars as above described, it will beA seenthat each barV is locked by two of the other bars and that they are thusfirmly retainedin position, securing the glass from accidentaldisplacement.V

If it is desired to remove the glass, the bars may be removed in thereverse order,'first forcing the upper end of the bar 42 outwardsufficiently to clear the end of the bar 43. A rod or pin may then beinserted in an adjacent hole 48 and the bar 43 may be thus drawn out ofits groove 35. The bars 42, 41 and 40 may thereafter be removed bysimilar use of a pin inserted in holes 48.

It should be particularly noted that the insertion or removal of theglass may be performed without removingthe sash from the window casing,an item lof very substantial importance, particularly when the inventionis used in connection with highly finished structures, such as a railwaycar.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed otherwise than as setforth in the claims but what I claim is Y l. A metal window sashcomprising a sash frame having grooves along its inner edges andhavinginwardly projecting flanges, and locking bars seated in saidgrooves and effective to hold a glass in position against said flanges,said bars having locking adjustment with each other by which they aremutually retained in glass-holding position, and one of said bars beingresilient to permit movement thereof out of locking position.

2. A metal window sash comprising a sash frame having grooves along itsinneredges and having inwardly projecting flanges, and lockingbars-seated in said grooves and effective to hold a glass in positionagainst said flanges, certain of said bars having notched ends effectiveto receive the ends of other bars and preventing "inward movementthereof from glass-holding position and one of said other Abars beingresilient to permit retention thereof in operative position and beingyieldingly movable from its position of engagement with an adjacentnotched end.

3. A metal window sash comprising a sash frame having groovesalong itsinner edges and having inwardly projectingflanges, and locking barsseated in said grooves and effective to hold a glass in position againstsaid flanges, said frame comprising recessed frame members connected atthe corners and held in alignment by reinforcing corner membersextending adjacent to and beyond said grooves which fit in said recessesand extend as integral units along said recesses at each side of eachcorner of said frame.

4. A metal window'sash comprising a sash frame having'grooves along itsinner edges and having inwardly projecting flanges and lock-ing barsseated in said grooves and effective to hold a glass in position againstsaid flange, each of said bars having Vits ends in engagement With twoadjacent bars, one of said bars being resilient and shaped to permitflexing into and out of engagement with its adjacent bars.

5. A metal window sash comprising a sash izo isc

frame having grooves along its inner edges and having inwardlyprojecting flanges, and locking bars seated in said grooves andefi'ective to hold a glass in position against said flanges, two of saidbars having notched ends efective to receive the ends of other hars, an#other of said bars having rounded ends effective to engage the notchesin adjacent bars and another of said bars having squared ends adapted tofit the remaining notches in adjacent bars, said notches, rounded endsand squared ends eii'ective to form a lock and prevent inward movementof the bars from glass-holding position.

In testimony whereof I have hereunto affixed my signature. CHARLES H.TURNER.
